Final Report

My project is about black holes and their effects on the rest of the universe. Einstein's general theory of relativity describes gravity as a curvature of spacetime caused by the presence of matter. If the curvature is fairly weak, Newton's laws of gravity can explain most of what is observed. For example, the regular motions of the planets. Very massive or dense objects generate much stronger gravity. The most compact objects imaginable are predicted by General Relativity to have such strong gravity that nothing, not even light, can escape their grip.

Here are some good reasons:

1.Human curiosity: they are among the most bizzare objects thought to exist in the universe.

2.They should be strong sources of gravitational waves.

3.As such, black holes should reveal much about gravity, a fundamental force in the cosmos.

4.Confirmation that they exist will strengthen confidence in current models of cosmic evolution, from the Big Bang to the present universe.

Black holes are all very well in theory, but if they really exist, how do they form?

Scientists today call such an object a black hole. Why black? Though the history of the term is interesting, the main reason is that no light can escape from inside a black hole: it has, in effect, disappeared from the visible universe.

Do black holes actually exist? Most physicists believe they do, basing their views on a growing body of observations. In fact, present theories of how the cosmos began rest in part on Einstein's work and predict the existence of both singularities and the black holes that contain them. Yet Einstein himself vigorously denied their reality, believing, as did most of his contemporaries, that black holes were a mere mathematical curiosity. He died in 1955, before the term "black hole" was coined or understood and observational evidence for black holes began to mount.

In my computer program, you will be able to type in some statistics and see how it would effect the pull of gravitation, mass, and other certain types of aspects in a planet. It will print out the calculations and order them in most drastic change to most inapparent change. All you would have to do was enter the variables For example, what would the effect be on Jupiter if a black hole was present near it? Would the pull of gravity on it be changed, would itŐs orbit be changed, would the color and the shape of the planet be changed at all?

As of now, I have been successful in identifying the pull of certain black holes, the present state of Earth, Mars, Jupiter, Saturn, Pluto, Venus, Uranus, Neptune and Mercury. Event horizons and a few other features would be included. I have also gathered data from previous effects of black holes on certain parts of the universe. I will incorporate these statistics into a computer program. I am expecting to have a successful program that would make it easy to figure out what the effects of a black hole would be on the rest of the universe.
